Cycloalkanes a strong candidate for reducing aviation emissions

LIVERMORE, Calif. — Scientists at Sandia National Laboratories have released data that could play an important role in the future development of cleaner and more sustainable aviation fuel. In collaboration with researchers at Los Alamos National Laboratory, the team explored the physical properties of cycloalkanes, or molecules composed of hydrogen and carbon atoms arranged in […]

Truman and Hruby 2022 fellows explore their positions

ALBUQUERQUE, N.M. — Postdoctoral researchers who are designated Truman and Hruby fellows experience Sandia National Laboratories differently from their peers. Appointees to the prestigious fellowships are given the latitude to pursue their own ideas, rather than being trained by fitting into the research plans of more experienced researchers. To give wings to this process, the […]

Sandia uncovers hidden factors that affect solar farms during severe weather

ALBUQUERQUE, N.M. — Sandia National Laboratories researchers combined large sets of real-world solar data and advanced machine learning to study the impacts of severe weather on U.S. solar farms, and sort out what factors affect energy generation. Their results were published earlier this month in the scientific journal Applied Energy. Hurricanes, blizzards, hailstorms and wildfires […]

A song of ice and fiber

ALBUQUERQUE, N.M. — Sandia National Laboratories researchers are beginning to analyze the first seafloor dataset from under Arctic sea ice using a novel method. They were able to capture ice quakes and transportation activities on the North Slope of Alaska while also monitoring for other climate signals and marine life. The team, led by Sandia […]

Finding fire and ice: Modeling the probability of methane hydrate deposits on the seafloor

RALEIGH, N.C. — Methane hydrate, an ice-like material made of compressed natural gas, burns when lit and can be found in some regions of the seafloor and in Arctic permafrost. Thought to be the world’s largest source of natural gas, methane hydrate is a potential fuel source, and if it “melts” and methane gas is […]

International research team begins uncovering Arctic mystery

ALBUQUERQUE, N.M. — Something lurks beneath the Arctic Ocean. While it’s not a monster, it has largely remained a mystery. According to 25 international researchers who collaborated on a first-of-its-kind study, frozen land beneath rising sea levels currently traps 60 billion tons of methane and 560 billion tons of organic carbon. Little is known about […]

Exploring Arctic clues to secure future with new Sandia, university partnership

ALBUQUERQUE, N.M. — The Arctic is undergoing rapid change, with sea ice melting and temperatures rising at a faster pace than anywhere else in the world. Its changing environment affects global security, politics, the economy and the climate. Understanding these changes is crucial for shaping and safeguarding U.S. security in the future, Sandia scientists say. […]

Effects of climate change on communally managed water systems softened by shared effort

ALBUQUERQUE, N.M. — Shared fates and experiences in a community can help it withstand changes to water availability due to climate change, a recent study by Sandia National Laboratories researchers found. “During our research, a community’s ability to withstand natural and social pressures was routinely pinpointed to the fact that the people who live there […]

Cool flames for better engines

Sandia researchers use Direct Numerical Simulations to enhance combustion efficiency and reduce pollution in diesel engines LIVERMORE, Calif. — A “cool flame” may sound contradictory, but it’s an important element of diesel combustion — one that, once properly understood, could enable better engine designs with higher efficiency and fewer emissions. Sandia National Laboratories mechanical engineer […]

Understanding hazardous combustion byproducts reduces factors impacting climate change

Sandia researchers focus on soot, furans, oxygenated hydrocarbons LIVERMORE, Calif. – Researchers at Sandia National Laboratories’ Combustion Research Facility are developing the understanding necessary to build cleaner combustion technologies that will in turn reduce climate impact. Their work focuses on understanding the oxidation chemistry of organic carbon species critical to many processes including controlling emissions […]

Geophysicist Marianne Walck named vice president of Sandia’s California laboratory

New role includes leadership of Energy and Climate program LIVERMORE, Calif.—Sandia National Laboratories has appointed Marianne Walck vice president of Sandia’s California laboratory. She replaces Steve Rottler, who will become the deputy director and executive vice president for National Security Programs. Both changes are effective March 6. “I am pleased to welcome Marianne to Sandia’s […]

New project is the ACME of computer science to address climate change

ALBUQUERQUE, N.M. — High performance computing researchers at Sandia National Laboratories are working with the Department of Energy (DOE) and other national laboratories and institutions to develop and apply the most complete climate and Earth system model, to address the most challenging and demanding climate change issues. Accelerated Climate Modeling for Energy, or ACME, is […]

Hard cold work and unsung science heroes

Data for climate simulations doesn’t come easy ALBUQUERQUE, N.M. —The Sierra went down over the Arctic Ocean, about 60 miles from the northernmost tip of North America. One moment the unmanned aerial vehicle (UAV) with its 20-foot wingspan was up in the sky, gathering “hard” data over frozen terrain to help climate scientists in comfortable offices […]

New Mexico group wins money to educate public on climate science

ALBUQUERQUE, N.M. — With interest in climate change heating up, a New Mexico group has won a $3,000 American Chemical Society Presidential Climate Science Challenge Grant to help educate the public on climate science issues. The award to the Central New Mexico section of the ACS will help the group begin to tackle a longstanding […]

Study rebuts hypothesis that comet attacks ended 13,000-year-old Clovis culture

ALBUQUERQUE, N.M. — Rebutting a speculative hypothesis that comet explosions changed Earth’s climate sufficiently to end the Clovis culture in North America about 13,000 years ago, Sandia lead author Mark Boslough and researchers from 14 academic institutions assert that other explanations must be found for the apparent disappearance. “There’s no plausible mechanism to get airbursts […]
